'tain :novel features .of construction, .combination .and arrangement ;of parts and portions, as will be: hereinafter describedindetail andparticularly set :forth in "the-appended claims, ;reference being had to the accompanying drawings and to "the characters of reference thereon, gforming apart .of.thisapplication,ginwhich:

Fig. :1 is .a fragmentary side elevational ,view .of my -.window louver screen and irame, showing :portions there!) .broken :away and in section to :amplify the illustration; Fig. 2 is an enlarged ;f-ragmentary sectional view, taken from the line .-2-T-2 of .Fig. 11; and Fig.3 is afragmentarysectional1view,-taken fromthe line '3-3 of Fig.v 1.

Similar-characters Qf.:reference refer to similar parts and portions throughout the several views ofgthe drawings.

The .frame :I screen -2,'screen locking-members 3, molding channels 4, 5, 6 and i1, and the screws 18 aconstitutethe principal parts and -portions of .mywind'owlouver screen and frame.

Theframe 1 is .a. rectangular frame, composed of a cross-sectionalshape, asshown in Fig. -2 of gthedrawings; wherein theouteredge of theirame isqprovidedwith a channel portion l a, having an open side 11), provided with a;folded-.edge portion to, which is directedtoward-the enclosed side of :the-channel la. The cross-sectional structure of this frame :I also incorporates .an integral ;rec-

.tangular in cross-section stressabearing'structure id, 'which is :inwardly of the channel Ia, :and which supports tension of the screen? .lockedin :the .channel -l,a by means of the "screen locking members-3.

The screen locking members -3 :are circular in cross-section; ormay be angular .incross-section, if desired, and extend along-each straight-side of :the frame I i-nthe'channel portions'lagandjfrictionally lock :the edge portions 2a of thelouver screen 2 at two-opposed sides of the screen-frame l parallel ,to thelouver screenslatsie and transversely of theintegral tension stripslda Thus, the tension strips -;2d are engaged by the..screen locking members 3 and are frictionally ghel'd, which maintains said strips 12d in tension .for

"holding the screen "2 tight and secure 'on the frame-1 The screenfZ-is asubstantially conventional louver-screen, havinga plural-ity"of---rows"of louver; portions-Q b, which are: angularly 'disposed, iasishowniniEig 2 -of the drawings. "The edges lc of the louver screen 2, disposed at right angles to the edges 2a interlocked by the screen locking members 3, are arranged in overlapped relationship with the inwardly extending edge portions 4a and Ed of the molding channels 4 and 5. Thus, tension in the louver screen 2 is transversely of the louvers and longitudinally of the rows of louvers 21), all as shown best in Fig. 1 of the drawings.

The molding channels 4, 5, 6 and I are all substantially similar in cross-section, and therefore the molding channel 4, as shown in Fig. 3, will be described herein for the purpose of disclosing the shape of all of the channels 4, 5, 6 and I. At the edge portion 4a of the molding channel 4, the overlapped relationship with the edge 20 of the screen 2 is sufficient to retain the screen 2 securely against the rectangular in cross-section structure Id of the frame |,which is integral with the channel la, and the opposite edge 41) of the molding channel 4 is nearer the enclosed side 40 of the molding channel 4, so that the edge 4a may be placed initially in overlappin relationship with the edge 20 of the screen 2, before the edge 4?) of the channel 4 engages the normally enclosed side of the channel portion la of the frame I. Thus, interference with and distortion of the screen 2 is substantially eliminated when assembling the molding channels 4, 5, 6 and l on the frame I and screen 2.

It will be noted that the screen lockin members 3 may be made of plastic, metal, or other similar soft material, and that the screws 8, which are self-threading screws, extend through the molding channels 4, 5, and 7 and into the outer leg of the channel portions Id of the frame l. At two opposite sides of the frame I, these screws 8 extend into the screen locking members 3, and these screen locking members 3, being circular in cross-section, are pressed into the channel portions I-a of the frame I past the edge Io at the center of said screen locking members 3, so that they are efiectively locked frictionally in the channels la.

The operation of my window louver screen and frame is substantially as follows: When installing the screen 2, the screen locking members 3 are forced downwardly into the channel Ia, causing frictional engagement of the screen 2 with the screen locking members 3 concurrently to the downward movement of the screen locking members 3 in the channels la of the frame I. This locking action causes stretching of the screen 2 and creates tension, which is applied to the rectangular in cross-section frame portions Id, which renders the channel portion Ea free to frictionally hold the screen 2 and screen locking members 3 in secure position without undue stress on the actual resilient portion of the channel Ila, which engages the normally outer side of the screen locking members 3.

It will be noted that the rows 2b of the louvers of the screen 2 may be equally spaced relatively to the edges 4a and 5a of the molding channels 4 and 5, and that the overlapping edges 40!. and 5a of the molding channels 4 and 5 provide for neat arrangement of the louvers of the screen 2 without deformation thereof.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction,

4 combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a window screen frame, a rectangular frame having opposed sides provided with a crosssection comprising an open channel adjacent the rectangular marginal portions of said frame, a rectangular in cross-section structural means in connection with said channel portion and extending inwardly of said channel portion, away from said marginal portions, screen extending intermediate said opposite sides and having rows of parallel louver slats separated by tension means extending to the marginal limits of said screens, and locking means extending laterally of said tension means frictionally engaging said screen including said tension means at two opposite parallel edges and holding the same in said channel portions whereby said tension means is engaged and maintained in tension by said locking means, the remaining parallel edges of said screen extending in overlapped relationship with said frame, and molding channels having parallel legs extending around the edges of said frame and overlapping said screen.
